* GameMode supports the following client functions

* -1 if the request failed
*
* int gamemode_request_end() - Request gamemode ends
* 0 if the request was sent successfully
* -1 if the request failed
*
* GAMEMODE_AUTO can be defined to make the above two functions apply during static init and
* destruction, as appropriate. In this configuration, errors will be printed to stderr
*
* int gamemode_query_status() - Query the current status of gamemode
* 0 if gamemode is inactive
* 1 if gamemode is active
* 2 if gamemode is active and this client is registered
* -1 if the query failed
*
* int gamemode_request_start_for(pid_t pid) - Request gamemode starts for another process
* 0 if the request was sent successfully
* -1 if the request failed
* -2 if the request was rejected
*
* int gamemode_request_end_for(pid_t pid) - Request gamemode ends for another process
* 0 if the request was sent successfully
* -1 if the request failed
* -2 if the request was rejected
*
* int gamemode_query_status_for(pid_t pid) - Query status of gamemode for another process
* 0 if gamemode is inactive
* 1 if gamemode is active
* 2 if gamemode is active and this client is registered
* -1 if the query failed
*
* const char* gamemode_error_string() - Get an error string
* returns a string describing any of the above errors
*
* Note: All the above requests can be blocking - dbus requests can and will block while the daemon
* handles the request. It is not recommended to make these calls in performance critical code
